Science is predicated on a creator. It's silly to pretend otherwise.
Science doesn't pretend to argue about ultimate causes, but it does attempt to analyze currently effective causes. The research program that would support ID is indistinguishable from one that would support evolution. There would be no difference in the materials or methods of research. ID proponents might choose different topics on which to spend research dollars, but they would have to have the same goal.
And that goal would be to find the natural chain of causes for phenomena. You cannot assert that something is designed without attempting to rule out natural causes. If and when you get down to bedrock causes -- the theory of everything -- then you can have a deep discussion of why things are the way they are.
